Specification of Letters Patent.-

Applisation filed January 31. 1907- Berlal No. 355.124- I To all whom itmay concern:

. Be it known that I, HARRY W. Moons, a citizen of the United States,residing at Atchison, in the county of Atchisonand State of Kansas, haveinvented a new and useful 1 Chair or Seat, of which the following is aspecification.

This invention relates to folding chairs or seats of that general classprincipally de-' signed for use in theaters, schools or similar placesand has for its object to providea comparstively simple andinexpenslvedevice of this character capable of belng readily folded tofacilitate cleaning beneath and around the chair and also forconvenience in storing and shipping the same. u

A further object of the invention is to provide a chair or seat having adesk combined therewith and adapted tobe folded doWn-. wardly inengagement With the back of the seat when not in useor when cleaningbeneath the same. I A still further object of the invention is togenerally im rove this class of devices so as to increase t eir utility,durability and efficiency.

Further objects and advantages will ap pearin the following descriptionitbeingun- 35- structed in accordance with my invention.

- Fig. 2 is a-f'rcnt derstood thatvarious changes 1n form, promay beresorted'to within'thescope of the "appgnded claims.

Pivotally mounted for vertical movement on theupnghts or standards are intersecting legs 8 and 9. The pivot pins 10'ofthe intersecting legs are cesses 1 1 formed in the uprights or standards5 so that when the chair is folded the pivot thus permit a slightvertical movement of the able clam ing nuts which bear against theadjacent" aces of the standards and sup ort the legs in elevated.position when the 0 air is folded.

I in this fOIIIlQf thedevice the intersecting legs 27 and 28 are pivotally mounted for slidingmovement n standards or supports similar in construction to thestandards shown in Fig. 1 of the drawings. The legs 28 are preferablyformed in two sections, the lower section ol each of which is providedwith a locking recess 29 for the reception of the adjacent end of" theback portionBU while the upper section of the pivoted leg is pivotallyconnected at 31' with-the seat portion 32. The siderails 33 and seatportion 32 engage locking recesses 34 formedin theupp'er ends-sof'thelegs 27 whereby downward pressure exerted on the seat when the latter isin use will act to thrust the side rails 33 and the upper ends of thepiv- ,oted legs 27 and 28 forward, and thus-move.
